Please Help!
I want to correct a focusing issue (Little backfocus at 18mm - Frontfocus at 50mm on a Sigma 18-50 2.8 DC EX Macro HSM lens.
I already (successfully) did the correction on a Sigma 70mm Macro, but the mechanism is completely different.
Under the large rubber zoom belt, there are 2 covered holes (See pictures in attachment): one containing the Zoom Brush, and a second containing the Zoom Connection Pin/Collar. I allready tried to losen the zoom connection pin/collar, in the hope it would give me a correction mechanism, but I can't find it...
Could someone please, please point me in the right direction?
Any help greatly appreciated!!
Thanks in advance,
Peter.

I think might be not the best place to ask about AF lenses, people gathering here are mostly experienced and interested in classical cameras, as defined on the main forum page:
PLEASE DO NOT POST...questions unrelated to repair of cameras from the above mentioned camera eras; questions about modern P&S's (point and shoot), modern automatic cameras (if it's auto focus it's modern!);.
This lens might be simply too new for anyone here to have ever touched it.
